From Wikipedia, the free encyclopedia. A mucous membrane or mucosa (plural, mucosae or mucosas; Latin tunica mucosa) is a lining of mostly endodermal origin. It consists of an epithelium (a layer, or layers of epithelial cells) and an underlying lamina propria of loose connective tissue.f the lining is torn or broken, mucus is incapable of performing its roles of preventing infection and retaining tissue moisture levels. In the female, the glans clitoridis and the clitoral hood have mucous membranes.
What is the difference between RA(Registration Authority) and CA(Certifying Authority)? RA interacts with the subscribers for providing CA services. The RA is subsumed in the CA, which takes total responsibility for all actions of the RA.
The certification authority is the primary component of a PKI. Most PKIs will have more than one CA. A CA is simply a server that runs some sort of certificate services software. An example is the Microsoft Windows 2000 certificate services, which is included with the Windows 2000 server operating systems.
